Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a portable information recording and reproducing device, more specifically,
The present invention relates to a relatively small portable information recording and reproducing device that is convenient to carry.

[Prior Art] When traveling with a camera, the user often also carries a spare film. Most conventional silver halide film cameras use film stored in a cartridge, so it is impossible to carry spare film attached to the camera body due to lack of space in the camera body. The reality was that he carried his camera and film separately.

[Problems to be solved by the invention] By the way, in an electronic camera that can magnetically record a subject image and reproduce it in a viewfinder, a thin sheet-like magnetic disk is housed as a magnetic recording medium. A flat magnetic disk pack is used. Therefore, if this magnetic disk pack is to be carried alone, for example in a clothing pocket, it will be bulky due to its relatively large area.
It is clear from experience that when the magnetic disk pack is attached to a structure of a size equal to or larger than the magnetic disk pack, the size of the structure is almost the same as the original size. However, since there was no idea of attaching a spare film to the camera body in conventional silver halide film cameras, the idea of attaching a spare magnetic disk pack to the camera body also existed for electronic cameras. This made it inconvenient to carry a spare magnetic disk pack.

On the other hand, electronic cameras have been gradually becoming smaller in recent years to make them more portable, but in reality, with such miniaturized electronic cameras, it is difficult to securely hold the camera body and take stable pictures. In order to do this, a grip part that is larger than a human hand is often attached to the camera body.

Furthermore, the same applies not only to electronic cameras but also to portable information recording and reproducing devices that use laser light to record and reproduce information on optical discs.

The present invention has been made in view of the above circumstances, and it is possible to carry the recording medium integrally with the main body of the recording/reproducing apparatus by holding the spare information recording medium in a grip section attached to the main body of the recording/reproducing apparatus. The purpose of the present invention is to provide a portable information recording and reproducing device that can perform the following functions.

[Means and effects for solving the problems] The portable information recording/reproducing device of the present invention is provided with a holder portion on the grip portion attached to the main body of the information recording/reproducing device, and the holder portion is provided with a holder portion for storing spare information. A recording medium is retained.

[Example] First, an example of the present invention will be described using FIGS. 1 to 4.

In the main body 1 of the electronic camera shown in FIG. 1, a grip portion 1a for gripping the main body 1 with the right hand is formed adjacent to a lens barrel 2 and protrudes forward. In order to make this electronic camera convenient to carry, the main body 1 is made as compact as possible, and the size of the gripping portion 1a is therefore small, making it difficult to grip as it is. Therefore, it is possible to use the main body 1 alone, but in order to be able to grip the camera main body 1 more stably and take pictures, the grip part 1a of the main body 1 has a part slightly larger than the grip part 1a. It is designed to be used by attaching a large grip part 3.

This grip part 3 is connected to the grip part 1a of the camera body 1.
It is attached with screws 4 covering the front and right side surfaces of the gripping portion 1a. The front surface of the grip part 1a of the camera body 1, which faces the grip part 3, is formed into a substantially curved shape, and the right side surface of the grip part 1a is rectangular, with most of the center part being slightly elongated, as shown in FIG. It is formed on the plane 5 of the shape, and the same plane 5

Surface-shaped edges 6a, 6b, and 6c are formed on the upper side and both left and right sides of the plane 5, respectively, and the edges 6a, 6b, and 6c are sloped gradually downward from the plane 5 outward. In other words,
The flat surface 5 has a surface shape that projects toward the grip portion 3.

The shape of the outer side of the grip part 3 is formed into a smooth curved shape so that it is easy to grip when the grip part 3 is attached to the camera body 1. The shape of the grip is similar to that of the grip part 1 of the main body 1.
It is formed in a surface shape corresponding to the front and right side surfaces of a. That is, the surface of the grip part 3 facing the front surface of the gripping part 1a is formed in a concave shape, and the surface facing the right side surface of the gripping part 1a is formed in the shape shown in FIGS. 3 and 4. . Next, based on FIGS. 3 and 4,
The shape and internal configuration of the grip portion 3 will be explained in more detail.

In FIGS. 3 and 4, the grip portion 3 is adapted to accommodate a spare magnetic disk pack 8 on the side facing the right side surface of the grip portion 1a of the camera body 1. As shown in FIGS. That is, in the grip part 3, the surface facing the flat surface 5 of the gripping part 1a is a restricting surface that allows the outer edge to come into close contact with the flat surface 5, and a magnetic field formed on the inner side of the restricting surface is formed on a surface one step lower than this. A pack storage section 9 for storing the disk pack 8 is provided. The edges 10a, 10b, 10c in three directions around the regulating surface have an inclined surface shape that gradually becomes higher toward the outside so that they can face and come into close contact with the edges 6a, 6b, 6c of the main body 1, respectively. is formed. A notch 11 is formed from an inner part of the center of the edge 10a to the pack storage section 9, and is used as a finger rest for taking out the magnetic disk pack 8 stored in the storage section 9.

A through hole 12 for attaching the screw 4 is formed in the center of the pack storage section 9, and the grip section 3 is inserted into the through hole 12.
The shaft portion of the screw 4 inserted through the outside of the box protrudes into the pack storage section 9. An E-ring 13 is attached to the base of the shaft of the screw 4 exposed in the pack storage section 9 to prevent it from coming off. The head of the screw 4 is placed in a recess 12a formed on the outside of the grip part 3, and a surface having a groove 4a for rotating the screw 4 with a coin or the like is exposed on the outside of the grip part 3. ing. Additionally, leaf springs 14 and 15 are provided within the pack storage section 9 to stably hold the magnetic disk pack 8 within the storage section 9. The leaf spring 14 is for pressing the magnetic disk pack 8 in the thickness direction, and is arranged in a recess 16 formed on the bottom surface of the pack storage section 9, and one end of the leaf spring 14 is prevented from rotating by a boss 17 and a screw 18. The other end is formed into a fork shape, and reaches a position around the shaft of the screw 4 while floating above the bottom surface of the pack storage section 9. The leaf spring 15 is for pressing the magnetic disk pack 8 in the surface direction, and is disposed on the side surface of the pack storage section 9 facing the above-mentioned notch section 11, and one end of the leaf spring 15 is inserted into a recess at one end of the same side surface. The leaf spring 15 is fixed and prevented from rotating by a boss 19 and a screw 20, and the other end reaches the other end on the same side, and the central part of the leaf spring 15 between them projects inside the pack storage part 9.

Further, at the bottom of the pack storage section 9, a see-through window 21 made of transparent plastic or the like is provided so that the outside of the grip section 3 can see whether or not the magnetic disk pack 8 is stored.
is buried. It is desirable that the position of the transparent window 21 corresponds to a display label (not shown) affixed to the magnetic disk pack 8 when the magnetic disk pack 8 is stored in the pack storage section 9 .

When carrying the electronic camera configured in this manner, the shaft of the screw 4 of the grip section 3 is inserted through the hole of the disk hub 8a of the spare magnetic disk pack 8 (see FIGS. 1 and 3). , this magnetic disk pack 8 is placed in the pack storage section 9.

At this time, due to the biasing force of the leaf spring 15, the magnetic disk pack 8 is pressed against the side surface of the pack storage portion 9 where the notch 11 is formed, and its position in the surface direction is restricted. At this time, the magnetic disk pack 8 is attached to the leaf spring 1.
Due to the urging force of 4, it is slightly lifted from the bottom surface of the pack storage section 9, but as it is, the surface on which the magnetic disk pack 8 is placed faces the right side of the grip section 1a of the camera body 1, and the same When the grip part 3 is pressed against the grip part 1a with the shaft of the screw 4 aligned with the screw hole 7 on the side surface, the magnetic disk pack 8 resists the biasing force of the leaf spring 14 and presses against the flat surface 5 of the grip part 1a. The bottom surface of the pack storage section 9 is pressed against the side, thereby regulating the position in the thickness direction. Therefore, in this state, when the head of the screw 4 is rotated and tightened with a coin or the like, the threaded portion of the screw 4 is screwed into the screw hole 7, and the edge 6a of the gripping portion 1a is screwed.

Edges 10a and 10b of the grip portion 3 are shown at 6b and 6c.

The camera body 1 and the grip part 3 are fixed with the parts 10c in close contact with each other.

When taking out the magnetic disk pack 8, the grip part 3 is removed from the camera body 1 by rotating the screw 4 in the loosening direction, so that the magnetic disk pack 8 can be easily taken out from the pack storage part 9. When traveling, for example, a spare magnetic disk pack can be taken out and a recorded magnetic disk pack can be stored in the pack storage section 9 instead.
