Description

  The present invention is an image forming apparatus such as a copying machine, a facsimile machine, a printer, and a printing apparatus, and includes a first opening and closing body such as a scanner that can be opened and closed with respect to the image forming apparatus body, and an opening and closing operation with respect to the first opening and closing body. An image forming apparatus including a possible pressure plate and a second opening / closing body such as an ADF, and the first opening / closing body and the second opening / closing body provided in the image forming apparatus are simultaneously opened. It is related with the control member for controlling.

  Conventionally, image forming apparatuses such as copiers, facsimiles, printers, and printing apparatuses are externally provided with a door that opens when accessing the inside of the image forming apparatus for replenishment of toner, jam processing, and other maintenance. ing. However, when the image forming apparatus is provided with a scanner due to a recent demand for downsizing of the apparatus, the door is omitted and the scanner is opened with respect to the main body of the image forming apparatus. A configuration that allows access to the inside or a configuration that allows access to the inside of the image forming apparatus by removing a member that is exposed by opening the scanner has come to be used.

  As described above, in the configuration in which the scanner is opened with respect to the image forming apparatus main body, a rotating fulcrum of the scanner is provided on the back side of the image forming apparatus as viewed from the user's standing position to improve the operability. In general, the image forming apparatus can be opened and closed in a manner of rotating with respect to the main body of the image forming apparatus.

  In such an image forming apparatus, when the scanner is of a type called a flat bed having a contact glass, a pressure plate for pressing a document and an automatic document feeder so-called ADF may be provided on the scanner. It is common.

  Even in such a configuration, in order to improve the operability of the pressure plate and the ADF, a rotation fulcrum of the pressure plate and the ADF is provided on the back side of the image forming apparatus as viewed from the user's standing position, and the pressure plate and the ADF are rotated. Can be opened and closed. Since the pressure plate and the ADF are disposed on the upper portion of the scanner, the pressure plate and the ADF are generally provided so as to be openable and closable with respect to the scanner.

  In such a configuration, when the image forming apparatus is installed with the back face of the image forming apparatus being close to or in contact with the wall, the image forming apparatus main body is opened with the pressure plate and the ADF open to the scanner. If the pressure plate or ADF is opened, the pressure plate or ADF may come into contact with the wall, and the pressure plate or ADF may be damaged or broken, or the wall may be damaged.

  In addition, even if the scanner is opened with the pressure plate or ADF closed, if the momentum is strong, the pressure plate or ADF can open, so the same possibility exists. Also, when the scanner is opened with the pressure plate or ADF closed, even if the scanner is opened slowly, for example, when the drive part such as the motor of the ADF is in the vicinity of the rotation fulcrum and the scanner is opened, the center of gravity of the ADF becomes the rotation fulcrum In cases such as exceeding ADF, the ADF or the like can open, so there is a similar possibility.

  Further, when the back surface of the image forming apparatus is not close to the wall, if the scanner and the pressure plate or ADF are opened at the same time, depending on the weight, balance, etc. of the scanner, the pressure plate and ADF, the image forming apparatus itself May fall backwards.

  Such a problem is not limited to the case where the rotating configuration is a scanner, a pressure plate, or an ADF, and the first opening / closing body that can be opened / closed with respect to the main body of the image forming apparatus and the first opening / closing body that can be opened / closed. Any image forming apparatus provided with a second opening / closing body may occur.

  Under such circumstances, in [Patent Document 1], the scanner is provided with a pressing member that engages in a switching manner in either the ADF or the image forming apparatus main body, and the scanner and the ADF are opened simultaneously. Technologies that can prevent this have been proposed. [Patent Document 2] proposes a mechanism for restricting the opening of the ADF when the upper body of the image forming apparatus is opened.

  In addition, [Patent Document 3] discloses a configuration in which the total opening angle between the image reading unit that opens with respect to the image forming apparatus main body and the document cover that opens with respect to the image reading unit does not exceed 90 degrees. , [Patent Document 4] discloses a configuration in which a spherical member that senses tilt is disposed at the hinge portion of the scanner to prevent the scanner from opening rapidly, and [Patent Document 5] discloses an image forming apparatus. A configuration is disclosed in which a scanner is opened when a scanner is held to lift the whole.

As shown in FIG. 2B, the image forming apparatus 100 may include a pressure plate 28 as a second opening / closing body instead of the automatic document feeder 22. Similarly to the automatic document feeder 22, the pressure plate 28 is also pivotally integrated with the reading device 21 by a shaft 26 and can be opened and closed with respect to the reading device 21. Further, like the automatic document feeder 22, a grip portion 27 is provided, and the grip portion 27 is gripped and rotated upward to open to the reading device 21 and expose the contact glass 21a. The remaining configuration is the same as that shown in FIG.

  With reference to FIG. 1, the configuration of the image stations 60Y, 60M, 60C, and 60BK will be described on behalf of the configuration of the image station 60Y including the photosensitive drum 20Y. Since the configuration of the other image station is substantially the same, in the following description, for the sake of convenience, a reference numeral corresponding to the reference symbol assigned to the configuration of the image station 60Y is attached to the configuration of the other image station. Further, detailed description will be omitted as appropriate, and those with Y, M, C, and K at the end of the reference numerals are configurations for forming yellow, magenta, cyan, and black images, respectively. Will be shown.

  The image station 60Y provided with the photoconductive drum 20Y is for cleaning the primary transfer roller 12Y and the photoconductive drum 20Y around the photoconductive drum 20Y along its rotation direction B1, which is the clockwise direction in the drawing. A cleaning device 70Y as a cleaning device, a charging device 30Y as a charging device as a charging device for charging the photosensitive drum 20Y to a high voltage, and a developing device as a developing device for developing the photosensitive drum 20Y A developing device 50Y. The developing device 50Y has a developing roller 51Y disposed at a position facing the photosensitive drum 20Y.

  The photosensitive drum 20Y, the cleaning device 70Y, the charging device 30Y, and the developing device 50Y are integrated to form a process cartridge. The process cartridge is detachable from the main body 99. Making a process cartridge in this way is very preferable because it can be handled as a replacement part, so that the maintainability is remarkably improved.

  With the configuration described above, the surface of the photosensitive drum 20Y is uniformly charged by the charging device 30Y as it rotates in the B1 direction, and corresponds to the yellow color by the exposure scanning of the beam LY from the optical scanning device 8. An electrostatic latent image is formed. The electrostatic latent image is formed by scanning the beam LY in the main scanning direction, which is a direction perpendicular to the paper surface, and performing sub scanning in the circumferential direction of the photosensitive drum 20Y by rotating the photosensitive drum 20Y in the B1 direction. This is done by scanning in the direction as well.

  The electrostatic latent image formed in this way is charged with the charged yellow toner supplied by the developing device 50Y, developed into a yellow color and visualized, and the yellow color toner obtained by development is developed. The toner image, which is a visible image, is primarily transferred to the transfer belt 11 moving in the A1 direction by the primary transfer roller 12Y, and foreign matters such as toner remaining after the transfer are scraped off and stored by the cleaning device 70Y. The drum 20Y is subjected to the next charging by the charging device 30Y.

  Similarly, toner images of the respective colors are formed on the other photosensitive drums 20C, 20M, and 20BK, and the formed toner images of the respective colors are transferred to the A1 direction by the primary transfer rollers 12C, 12M, and 12BK. 11 is sequentially transferred to the same position on the head.

  The toner image superimposed on the transfer belt 11 moves to the transfer portion that is the secondary transfer portion that is the position facing the secondary transfer roller 5 as the transfer belt 11 rotates in the A1 direction. Secondary transfer is performed on the transfer paper S.

  The transfer sheet S conveyed between the transfer belt 11 and the secondary transfer roller 5 is fed out from the sheet feeding device 23 and is transferred onto the transfer belt 11 by the registration roller pair 13 based on the detection signal from the sensor. The toner image is sent out at the timing when the leading end of the toner image faces the secondary transfer roller 5.

  When the toner images of all colors are collectively transferred and carried on the transfer paper S, the transfer paper S is transported in the C1 direction and enters the fixing device 6 and passes through the fixing portion between the fixing roller 62 and the pressure roller 63. The carried toner image is fixed by the action of heat and pressure, and a color image which is a composite color image is formed on the transfer paper S by this fixing process. The fixed transfer paper S that has passed through the fixing device 6 passes through the paper discharge roller 7 and is stacked on the paper discharge tray 17. On the other hand, the transfer belt 11 that has finished the secondary transfer is cleaned by a cleaning device to prepare for the next primary transfer.

  As shown in FIG. 3, in the image forming apparatus 100, the inside of the main body 99 can be accessed with the reading device 21 opened with respect to the main body 99. FIG. 4A shows a configuration example in which the discharge tray 17 is detached from the main body 99 together with the reading device 21 when the reading device 21 is opened, and the inside of the main body 99 is opened. In FIG. 5B, when the reading device 21 is opened, the paper discharge tray 17 can be detached from the main body 99. After the reading device 21 is opened, the paper discharge tray 17 is detached from the main body 99 and taken out, and the inside of the main body 99 is opened. A configuration example is shown.

  When the inside of the main body 99 is opened, the optical scanning device 8 can be taken out from the main body 99. When the optical scanning device 8 is taken out, the process cartridges respectively provided in the image stations 60Y, 60M, 60C, and 60BK are independent from each other. 99, it can be taken out upward. In addition, toner can be supplied to the image stations 60Y, 60M, 60C, and 60BK, and a paper jam can be processed on condition that the inside of the main body 99 is opened.

  As described above, the opening angle of the reading device 21 with respect to the main body 99 and the opening angle of the automatic document feeder 22 with respect to the reading device 21 are both approximately 90 degrees in consideration of the ease of each operation. .

  In such a configuration, assuming that both the reading device 21 and the automatic document feeder 22 can be opened at the same time as shown in FIG. When the rear side, that is, the upstream side in the direction D1 is set close to or in contact with the wall, the automatic document feeder 22 contacts the wall, and the automatic document feeder 22 may be damaged or broken, May be hurt.

  Further, even if the reading device 21 is opened with the automatic document feeder 22 closed, if the momentum is strong, the automatic document feeder 22 can be opened. Further, when the reading device 21 is opened with the automatic document feeder 22 closed, even if the reading device 21 is slowly opened, for example, the drive portion of the automatic document feeder 22 such as a motor is in the vicinity of the rotation fulcrum. If the reading device 21 is opened and the center of gravity of the automatic document feeder 22 exceeds the rotation fulcrum, the automatic document feeder 22 can be opened.

  Further, when the back surface of the image forming apparatus 100 is not close to the wall, if the reading device 21 and the automatic document feeder 22 are simultaneously opened, the overlap between the reading device 21 and the automatic document feeder 22 is avoided. Depending on the balance or the like, the image forming apparatus 100 itself may fall backward. The same applies to the case where the pressure plate 28 is used instead of the automatic document feeder 22.

  Therefore, as shown in FIG. 4A, the reading device 21 and the automatic document feeder 22 are arranged such that when the automatic document feeder 22 is open with respect to the reading device 21, the reading device 21 is not connected to the main body 99. In addition, as shown in FIG. 4B, the automatic document feeder 22 is prevented from opening with respect to the reading device 21 when the reading device 21 is open with respect to the main body 99. It is desirable.

  Therefore, as shown in FIG. 5, the image forming apparatus 100 regulates the opening of the reading device 21 with respect to the main body 99 when the automatic document feeder 22 is open with respect to the reading device 21, and also the main body 99. On the other hand, there is a restricting means 31 for restricting the automatic document feeder 22 from being opened with respect to the reading device 21 when the reading device 21 is opened.

  The regulating means 31 regulates the opening of the reading device 21 to the main body 99 in conjunction with the opening of the automatic document feeder 22 with respect to the reading device 21, and opens the reading device 21 to the main body 99. In conjunction with this, the automatic document feeder 22 is restricted from opening with respect to the reading device 21, and a shaft 32 a that is a first support member provided as a support member disposed in the reading device 21 and A shaft 32b that is a second support member, a lock member 33a that is a first restriction member that is rotatably supported by the reading device 21 by the shaft 32a, and a rotation that is rotatable to the reading device 21 by the shaft 32b. And a lock member 33b as a second restriction member as a supported restriction member.

  The restricting means 31 is also integrated with the automatic document feeder 22 and the hook 34a which is a first locking member that is integrated with the main body 99 and engages with the lower end of the locking member 33a. And a hook 34b as a second locking member as a locking member with which the upper end of the locking member 33b is engaged.

  The restricting means 31 also includes an automatic document feeder 22 which is a first control means as a control means engaged with the upper end of the lock member 33a, specifically, a lower surface 22a of the automatic document feeder 22 and The main body 99 as the second control means as the control means with which the lower end of the lock member 33b is engaged, specifically, the upper surface 99a of the main body 99 is provided.

  The lock member 33a is engaged with the hook 34a by rotating counterclockwise as the first direction around the shaft 32a from the position shown in FIG. The reading device 21 is restricted from opening with respect to the main body 99. The lock member 33a has a hook shape at one end, that is, an end that engages with the hook 34a, and is easily separated from the hook 34a when engaged with the hook 34a.

  The lock member 33b automatically engages with the hook 34b by rotating from the position shown in FIG. 5A in the clockwise direction as the second direction around the shaft 32b as shown in FIG. The document feeding device 22 is restricted from opening with respect to the reading device 21. The lock member 33b has a hook shape at one end, that is, an end that engages with the hook 34b, and is easily separated from the hook 34b when engaged with the hook 34b.

  The shaft 32a supports the lock member 33a at a position deviating from the center of gravity of the lock member 33a. More specifically, the position where the shaft 32a supports the lock member 33a is counterclockwise as shown in FIG. 5B from the position shown in FIG. It is a position that rotates in the direction. Therefore, the lock member 33a itself is counterclockwise as shown in FIG. 5B from the position shown in FIG. It functions as a first urging means as an urging means for urging to rotate. That is, the first biasing means is integrated with the lock member 33a.

  The shaft 32b supports the lock member 33b at a position deviating from the center of gravity of the lock member 33b. More specifically, the position where the shaft 32b supports the lock member 33b is clockwise as shown in FIG. 10C from the position shown in FIG. It is a position to rotate. Therefore, the lock member 33b is moved in the clockwise direction as shown in FIG. 10C from the position shown in FIG. It functions as a first urging means as an urging means for urging to rotate. That is, the first urging means is integrated with the lock member 33b.

  The hook 34a holds the lock member 33a when the lock member 33a is rotated clockwise about the shaft 32a from the position shown in FIG. 21 restricts the opening to the main body 99.

  The hook 34b automatically locks the lock member 33b when the lock member 33b rotates counterclockwise about the shaft 32b as shown in FIG. 10C from the position shown in FIG. The document feeding device 22 is restricted from opening with respect to the reading device 21.

  When the automatic document feeder 22 is closed with respect to the reading device 21, the lower surface 22a abuts on the other end, that is, the upper end of the lock member 33a, as shown in FIGS. The lock member 33a is rotated counterclockwise from the position with respect to the reading device 21 shown in FIG. 5 (a) against the turning bias by the first biasing means due to its own weight. When the automatic document feeder 22 is opened with respect to the reading device 21 as shown in FIG. 5B, the lock member 33a is in the position relative to the reading device 21 shown in FIG. It functions as a first displacement member as a displacement member that is displaced so as to allow rotation in the counterclockwise direction. Therefore, only when the automatic document feeder 22 is open with respect to the reading device 21, the lock member 33a loses the support by the lower surface 22a and rotates counterclockwise.

  When the reading device 21 is closed with respect to the main body 99 as shown in FIGS. 4A and 4B, the upper surface 99a is brought into contact with the other end portion, that is, the lower end portion of the lock member 33b. The weight of the paper device 22 resists the rotational urging by the first urging means and restricts the lock member 33b from rotating clockwise from the position with respect to the reading device 21 shown in FIG. When the reading device 21 is opened with respect to the main body 99 as shown in FIG. 11C, the lock member 33b is rotated clockwise from the position with respect to the reading device 21 shown in FIG. It functions as a second displacement member as a displacement member that is displaced to allow. Therefore, only when the reading device 21 is open with respect to the main body 99, the lock member 33a loses the support by the upper surface 99a and rotates clockwise.

  Therefore, in the image forming apparatus 100, the reading device 21 and the automatic document feeder 22 are opened simultaneously, that is, the reading device 21 is opened with respect to the main body 99 and the automatic document feeder 22 is opened with respect to the reading device 21. Is regulated and prevented.

  The first urging means and the second urging means may be provided in the regulating means 31 in the manner shown in FIG. In the example shown in the figure, the first urging means and the second urging means are provided integrally with the lock members 33a and 33b, respectively. It is provided as a weight 35b which is a second weight body as a body.

The lock members 33a and 33b are also urged to rotate counterclockwise and clockwise by the weights 35a and 35b.
Even when the weights 35a and 35b are provided, the lock members 33a and 33b are urged to rotate counterclockwise and clockwise respectively by their own weights as in the configuration example shown in FIG. can do.

  Moreover, the 1st biasing means and the 2nd biasing means may be provided in the control means 31 in the aspect shown in FIG. In the example shown in the figure, the first urging means includes a magnet 36a as a first magnet body integral with the lock member 33a, and the reader shown in the figure by the interaction of the magnet 36a. And a magnet 36b as a second magnet body that urges to rotate counterclockwise from the position with respect to 21. The second urging means is a first integral with the lock member 33b. A magnet 37a as a magnet body and a magnet as a second magnet body that urges the lock member 33b to rotate clockwise from the position relative to the reading device 21 shown in FIG. 37b. The magnets 36a and 36b have the same poles, for example, N poles, on the sides facing each other, and perform such rotation bias by generating an interaction that repels each other. The magnets 37a and 37b have the same poles, for example, N poles, on the sides facing each other. The magnets 37a and 37b perform the rotation bias by generating an interaction that repels each other.

  The first urging means and the second urging means have poles that are different from each other, for example, N pole and S pole, respectively. It may be what performs. The regulating means 31 shown in FIG. 7 also includes the first urging means and the second urging means in this example.

  The first urging means is configured to move the lock member 33a from the position with respect to the reading device 21 shown in the drawing by the interaction between the magnet 38a as a first magnet body integral with the lock member 33a and the magnet 36a. A hook 34a that is a magnet as a second magnet body that is biased to rotate in the clockwise direction, and the second biasing means is a first magnet body that is integral with the lock member 33b. The hook 38 is a magnet as a second magnet body that urges the lock member 33b to rotate clockwise from the position relative to the reading device 21 shown in the figure by the interaction between the magnet 38b and the magnet 38b. 34b. The magnets 38a and 34a have different poles on opposite sides, for example, an S pole and an N pole, respectively, and perform such a biasing force by generating an interaction that attracts each other. The magnets 38b and 34b have different poles on opposite sides, for example, an S pole and an N pole, respectively. The magnets 38b and 34b perform such a rotation bias by generating an interaction that attracts each other.

  The first urging means is constituted by a lock member 33a itself made of a magnetic body, specifically iron, and a hook 34a itself made of a magnet as a third magnet body. The urging means may be constituted by a lock member 33b itself made of a magnetic material, specifically iron, and a hook 34b itself made of a magnet as a third magnet body. As a result, while the number of magnets is suppressed, an attractive action is generated between the lock member 33a and the hook 34a by the action of magnetic force, and the lock member 33a is urged to rotate counterclockwise. In addition, thereby, while suppressing the number of magnets, the lock member 33b and the hook 34b are attracted to each other by the action of magnetic force, and urge the lock member 33b to rotate clockwise.

  The magnetic material is not limited to iron, but may be other materials. From the viewpoint of suppressing the number of magnets, the magnetic body may be any one of the lock member 33a and the hook 34a as a magnetic body, and either the lock member 33b or the hook 34b. As long as the material itself is made of a magnetic material. The magnet is not limited to any one of the lock member 33a and the hook 34a itself, and may be integrated with any one of them, or when the lock member 33a is a magnetic body, It may be a separate body from the hook 34a. Further, the magnet is not limited to any one of the lock member 33b and the hook 34b, and may be integrated with any one of them, or when the lock member 33b is a magnetic body. The hook 34b may be a separate body.

  In these configurations, as shown in FIG. 7, when the first magnet body and the second magnet body or the magnetic body and the third magnet body are attracted to each other and come into contact with each other, the lock is applied. In the configuration in which the member 33a and the hook 34a or the lock member 33b and the hook 34b are engaged, such an engagement state is easily maintained, and the reading device 21 or the automatic document feeder 22 is regulated. It is easy to maintain the power release in a regulated state, which is preferable.

  Moreover, the 1st biasing means and the 2nd biasing means may be provided in the control means 31 in the aspect shown in FIG. In the example shown in the figure, the first urging means has a spring 39a which is a first elastic body as an elastic body having one end locked to the lock member 33a and the other end locked to the reading device 21. The second urging means has a spring 39b which is a first elastic body as an elastic body having one end locked to the lock member 33b and the other end locked to the reading device 21. . The springs 39a and 39 are tension springs, and perform such a rotational bias by their elastic force.

  The elastic body may be a coil spring that is wound around the shafts 32a and 32b and performs the rotation bias, or a compression spring that is disposed at an appropriate position, such as a position opposite to that of the springs 39a and 39b. It may be a rubber other than a spring.

  In the example shown in FIG. 5, the first control means is constituted by the lower surface 22a which is the first displacement member. However, as shown in FIG. 6, the first control means is the other end of the lock member 33a. And a magnet 41a as a fourth magnet body integral with the lock member 33a, and the lower surface 22a at a position facing the magnet 41a in the position of the lock member 33a with respect to the reading device 21 shown in FIG. And a magnet 41b as a fifth magnet body.

  In the example shown in FIG. 5, the second control means is constituted by the upper surface 99a which is the second displacement member. However, as shown in FIG. 6, the second control means is the other end of the lock member 33b. And a magnet 42a as a fourth magnet body integral with the lock member 33b at the portion, and disposed on the upper surface 99a at a position facing the magnet 42a in the position of the lock member 33b with respect to the reading device 21 shown in FIG. And a magnet 42b as a fifth magnet body.

  The magnets 41a and 41b have different poles on opposite sides, for example, an S pole and an N pole, respectively. The magnets 41a and 41b are mutually attracting forces and have a magnitude that resists the rotational bias by the first biasing means. By generating the action, when the automatic document feeder 22 is closed with respect to the reading device 21 as shown in FIGS. 9A and 9C, the lock member 33a is shown in FIG. When the automatic document feeder 22 is opened with respect to the reading device 21 as shown in FIG. 5B, the counterclockwise rotation from the position with respect to the reading device 21 is restricted. The attracting force cannot resist the rotation bias by the biasing means, and the lock member 33a is allowed to rotate counterclockwise from the position with respect to the reading device 21 shown in FIG. Therefore, only when the automatic document feeder 22 is open with respect to the reading device 21, the lock member 33a loses support due to the attractive force of the magnets 41a and 41b and rotates counterclockwise.

  The magnets 42a and 42b have different poles on opposite sides, for example, S pole and N pole, respectively. The magnets 42a and 42b are mutually attracting forces and have a magnitude that resists rotational biasing by the second biasing means. By generating the action, when the reading device 21 is closed with respect to the main body 99 as shown in FIGS. 9A and 9B, the lock member 33b is against the reading device 21 shown in FIG. When the reading device 21 is opened with respect to the main body 99 as shown in FIG. 5C, the forces attracted to each other are separated by the biasing means. The locking member 33b is allowed to rotate clockwise from the position with respect to the reading device 21 shown in FIG. Therefore, only when the reading device 21 is open with respect to the main body 99, the lock member 33b rotates in the clockwise direction while losing support by the force with which the magnets 42a and 42b are attracted.

In these configurations, the lock member 33a is prevented from being exposed when the automatic document feeder 22 is opened with respect to the reading device 21, and the lock member 33b is prevented from being exposed when the reading device 21 is opened with respect to the main body 99. There is an advantage that the appearance is clean and the unlocking by the user operating the exposed lock members 33a and 33b can be prevented.
The fourth magnet body and the fifth magnet body may be configured to restrict the rotation by a force repelling each other.

  Further, when a magnet body is used for the first control means and the second control means, it may function as the first control means and the second control means in combination with the magnetic body attracted to the magnet body. Good.

  That is, the first control means is a magnet as a sixth magnet body disposed at the same position as the lock member 33a itself made of a magnetic material, specifically iron, and the magnet 41b shown in FIG. In addition, the second control means includes a lock member 33b itself made of a magnetic material, specifically iron, and a sixth control unit disposed at the same position as the magnet 42b shown in FIG. You may comprise with the magnet as a magnet body. Accordingly, while the number of magnets is suppressed, the lock members 33a and 33b and the magnets are attracted by the action of magnetic force, and the rotation of the lock members 33a and 33b is restricted.

  The magnetic material is not limited to iron, but may be other materials. From the viewpoint of suppressing the number of magnets, the magnetic body is one in which either the lock member 33a or the member disposed at the same position as the magnets 41b and 42b shown in FIG. 6 is a magnetic body. If it is good. When the magnet is disposed on the lock members 33a and 33b side, the magnet may be integrated with the lock members 33a and 33b.

  As shown in FIG. 9, when the lock member 33a is rotated counterclockwise from the position with respect to the reading device 21 shown in FIG. 9A, the lock member 33a holds the grip portion 25 as shown in FIG. There may be a shutter 43a as a first shutter portion to be disabled, and the lock member 33b is rotated clockwise from the position with respect to the reading device 21 shown in FIG. As shown in FIG. 5C, a shutter 43b may be provided as a second shutter portion that makes the grip portion 27 incapable of gripping.

  When the automatic document feeder 22 is not opened with respect to the reading device 21 and the reading device 21 is not to be opened with respect to the main body 99, the gripping portion 25 cannot be gripped and the reading device 21 is restricted from opening with respect to the main body 99. When the reading device 21 is opened with respect to the main body 99 and the automatic document feeding device 22 is not to be opened with respect to the reading device 21, the gripping portion 27 cannot be gripped and the automatic document feeding device 22 is moved with respect to the reading device 21. Since the opening is restricted, and it can be visually confirmed that the grip portions 25 and 27 cannot be gripped in a timely manner, the above-described problems are less likely to occur, and the lock members 33a and 33b are damaged. There is an advantage that it is suppressed or prevented.

  As shown in FIG. 10, the lock members 33a and 33b may be supported so as to be rotatable coaxially by a single shaft 32 as a support member. This has the advantage that the number of parts is reduced.

  In addition, each urging unit may be configured by appropriately combining a weight body, each magnet body, a magnetic body, and an elastic body in a combination other than the examples described above. Each control means may be configured by appropriately combining the displacement member, each magnet body, and magnetic body in combinations other than the above-described examples.

  As shown in FIG. 11, the restricting member may be configured by a single lock member 33. In this case, compared to the above-described examples, there are advantages that the number of parts is suppressed and that assembly can be facilitated.

  The lock member 33 is rotatably supported by the reading device 21 by a shaft 32 having a configuration corresponding to the above-described shafts 32a and 32b, and has a weight 35 as a configuration corresponding to the above-described weights 35a and 35b. It is urged to rotate counterclockwise.

Inclined surfaces 45a and 45b are formed at the lower end and the upper end of the lock member 33, respectively.
The hooks 34 a and 34 b are constituted by a main body 99 and a concave portion of the automatic document feeder 22, respectively.

  The control means abuts the main body 99 and the automatic document feeder 22 in which the lower end and the upper end of the lock member 33 abut each other in the position of the lock member 33 with respect to the reading device 21 shown in FIG. The lower end portion and the upper end portion of the lock member 33 are in contact with the contact portions 44a and 44b, respectively. Rotation regulation for maintaining the posture shown in the figure is performed.

  In this configuration, when the automatic document feeder 22 is opened with respect to the reading device 21 from the state shown in the figure, the automatic document feeder 22 is rotated clockwise about the shaft 26. At this time, first, the abutting portion 44b slightly rotates the lock member 33 clockwise, and then the abutment between the abutting portion 44b and the lock member 33 is released, and the rotation urging by the weight 35 is performed. As a result, the lock member 33 returns to the original state in which it comes into contact with the contact portion 44a.

  Further, when the automatic document feeder 22 is rotated, the lock member 33 is restricted by the contact portion 44a, so that the hook 34b and the lock member 33 are not engaged during the rotation. As shown in FIG. 12A, the automatic document feeder 22 opens with respect to the reading device 21.

  When the automatic document feeder 22 is opened with respect to the reading device 21 and the reading device 21 is opened with respect to the main body 99 as shown in FIG. Since the rotation restriction by is released, as shown in FIG. 3C, the rotation of the lock member 33 is caused by the rotation bias by the weight 35 in a state where the reading device 21 is slightly opened with respect to the main body 99. The lower end portion is locked to the hook 34a, and the reading device 21 is substantially restricted from opening with respect to the main body 99.

  When the reading device 21 is to be closed with respect to the main body 99 from the state in which the reading device 21 is slightly opened with respect to the main body 99 shown in FIG. The lock member 33 is slightly rotated in the clockwise direction against the rotational urging force of the weight 35, and then returns to the state shown in FIG.

  When the automatic document feeder 22 is to be closed with respect to the reading device 21 from the state in which the automatic document feeder 22 is open with respect to the reading device 21, the contact portion 44b contacts the inclined surface 45b. The lock member 33 is slightly rotated clockwise against the rotation bias of the weight 35, and then returns to the state shown in FIG.

  On the other hand, in the configuration shown in FIG. 11, when the reading device 21 is opened with respect to the main body 99 from the state shown in FIG. 11, the reading device 21 is rotated clockwise about the shaft 24. At this time, since the lock member 33 is restricted by the contact portion 44b, the hook 34a and the lock member 33 are not engaged during the rotation, as shown in FIG. 13 (a). The automatic document feeder 22 opens with respect to the reading device 21.

  When the automatic document feeder 22 is to be opened with respect to the reading device 21 with the reading device 21 opened with respect to the main body 99 as shown in FIG. Therefore, when the contact portion 44b slightly rotates the lock member 33 in the clockwise direction, the contact between the contact portion 44b and the lock member 33 is released. The upper end portion of the lock member 33 is hooked to the hook 34b in a state where the automatic document feeder 22 is slightly opened with respect to the reading device 21, as shown in FIG. The automatic document feeder 22 is locked and the opening of the automatic document feeder 22 with respect to the reading device 21 is substantially restricted.

  When the automatic document feeder 22 is to be closed with respect to the reader 21 from the state where the automatic document feeder 22 is slightly opened with respect to the reader 21 as shown in FIG. The state shown in FIG. 11 (a) or FIG. 11 after the contact portion 44b contacts the inclined surface 45b and slightly rotates the lock member 33 in the clockwise direction against the rotational bias of the weight 35. Return to.

  Further, when the reading device 21 is to be closed with respect to the main body 99 from the state where the reading device 21 is open with respect to the main body 99, the contact portion 44 a comes into contact with the inclined surface 45 a, and the rotation force of the weight 35 is urged. Then, the lock member 33 is slightly rotated clockwise, and then returns to the state shown in FIG.

  In the case where the restricting member is constituted by one lock member 33, the urging means is not limited to the weight 35, and can be the one shown in FIGS. FIGS. 14 and 15 show examples having urging means corresponding to the urging means shown in FIGS. 7 and 8, respectively, and corresponding reference numerals are assigned to the corresponding members (FIG. 8). “A” and “b” at the end of the indicated code are omitted). Since the operation and the like are the same as those shown in FIGS. 7, 8, and 11 to 13, the description thereof is omitted.

  Even when the restricting member is constituted by one lock member 33, the biasing means may be constituted by appropriately combining the weight body, each magnet body, the magnetic body, and the elastic body in combinations other than the above-described examples. The control means may also be configured by combining a displacement member, each magnet body, and a magnetic body. The first and second shutter members can also be applied so that the grip portions 25 and 27 cannot be gripped in the state shown in FIGS. 12 (c) and 13 (c), respectively.
