Description

  The present invention relates to a laser pointer capable of irradiating a screen or the like with laser light.

  Conventionally, many laser pointers that can irradiate a screen or the like with laser light have been proposed. Some have been proposed to have various functions and performances, such as those that have the ability to operate personal computers as well as those that irradiate lasers, and those that are waterproof and dustproof. (For example, refer to Patent Document 1).

  Further, all of the laser pointers currently on the market in Japan satisfy predetermined requirements. The predetermined requirements are those related to the outer shape and weight of the casing having a length of 80 mm or more and a weight of 40 g or more, or two or more cylindrical batteries of the so-called single to single 5 size defined in JIS8500. Various requirements are also imposed on the electrical specifications of the laser pointer, the use of the same thing, and things related to carrying and handling.

JP 2006-330208 A

  However, considering the fact that the length of the casing needs to be secured about 80 mm even when using a so-called single-size cylindrical dry battery having the shortest dimension at present, the conventional structure is If applied as it is, the current situation is that the casing itself must have a large diameter and have a built-in mechanism. On the other hand, as a user's needs, a slim shape that can be handled in the same manner as a writing instrument, such as being put in a pocket of clothes or a pen case, is recognized as an easy-to-handle shape for the user. In other words, even if such a laser pointer is reached, the casing is made as smart as possible so that it can be handled easily by the user by realizing a length and shape that can be handled in the same manner as such a writing instrument. It is demanded.

  In addition, it is conceivable that a laser pointer compacted like a writing instrument is provided with a clip so as to be carried like a writing instrument. However, provision of the clip may be a barrier to downsizing, in particular, downsizing of the casing length. Moreover, considering that the laser pointer exceeding 40 g is hooked using a clip in the same manner as the writing instrument as described above, it is considered that the external force applied to the clip itself is larger than that of the writing instrument, and is adopted for the writing instrument. If the same clip mode is applied to the laser pointer as it is, it is conceivable that the clip cannot act as well as the writing instrument.

  The present invention pays attention to such points, and a laser pointer having a shape that is easy for a user to handle by realizing a short size as much as possible while maintaining a slim shape within a currently allowable range. The purpose is to provide.

  In order to achieve such an object, the present invention takes the following measures. That is, the laser pointer according to the present invention has a cylindrical casing and a clip body extending along the extending direction of the casing from a protruding portion protruding from the peripheral surface of the casing, and a latch such as a pocket of clothes together with the casing. And a clip for hanging on an object.

  If this is the case, it is used in a conventional writing instrument or the like in which the clip is protruded in the longitudinal direction of the casing by extending the clip body from the protruding portion that protrudes the casing to the side. A shorter laser pointer can be configured as compared with the configuration employed. In addition, according to the present invention, since the projecting portion only has to have a volume sufficient to support the clip body, the longitudinal dimension is increased to provide the clip, and the interior of the clip is provided in the longitudinal direction. It is possible to provide a compact laser pointer that effectively avoids the casing having a large diameter by changing the arrangement of the structure.

  And as a structure for attaching a clip main body more firmly with respect to a casing, a clip has a clip main body and a block part holding the base end part of this clip main body. It is desirable to provide a clip housing portion for housing the portion.

  In addition, in order to ensure the support of the block portion, it is preferable that the clip housing portion has a shape that substantially covers the rising portion from the block portion of the clip body.

  Furthermore, in order to attach a block part more firmly with respect to a casing, it is preferable to weld a block part with respect to a clip accommodating part.

  On the other hand, in order to further improve the strength of the clip itself attached to the casing, it is desirable to provide the clip integrally by insert molding the clip body and the block portion.

  In order to effectively suppress the external force applied to the clip during use from affecting the mounting strength between the clip housing part and the block part, a deformation assist formed partially in the vicinity of the base end of the clip body It is desirable to provide a part.

  In order to further strengthen the engagement between the clip main body and the block portion, it is necessary to provide the clip main body with a retaining portion in which a predetermined portion in the block portion at the proximal end portion is partially formed in a compact manner. desirable.

  A mode in which the block portion is further screwed to a metal plate-like electrode provided in the casing as a specific configuration for making the attachment of the clip stronger by utilizing other configurations of the laser pointer. Can be mentioned.

  By using a dry battery that is considered to have a relatively heavy specific gravity in the laser pointer, the configuration to effectively suppress the external force applied when using the clip includes an irradiation unit that can irradiate the laser and an operation for irradiating the laser. The irradiation unit and the operation together with the battery storage unit that can store the dry batteries along the direction in which the cylindrical casing extends when the operation unit to be received is positioned near the one end of the casing, that is, the so-called tip side. A configuration in which the casing is positioned closer to the other end of the casing separated from the part, that is, closer to the proximal end can be exemplified. With such a configuration, the center of gravity of the entire laser pointer is brought as close as possible to the position where the clip is placed, so that the external force applied to the clip due to the deflection of the laser pointer when the clip is hooked on the object to be hooked is made effective. Can be suppressed.

  According to the present invention, since the projecting portion only has to be protruded by a volume sufficient to support the clip body, the longitudinal dimension is increased in order to provide the clip, and the interior of the clip is provided in the longitudinal direction. It is possible to provide a compact laser pointer that effectively avoids a casing having a large diameter due to a change in the arrangement of the structure.
