Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a two-part tape recorder in which the head board side and the reel shaft side are divided at the middle of the front and back.

[Prior art]

Conventional tape recorders have a head board, a capstan shaft, a pinch arm, etc. on the front side of a single board, and a reel shaft on the back side of the board.

Therefore, when a tape recorder is assembled, a large number of single parts are sequentially assembled onto one board, making it difficult to assemble, and the functions of each part cannot be adjusted or inspected unless all parts are assembled, and the assembly cost increases. It was hot.

Furthermore, if there is a partial change in the function, it must be reassembled from the beginning, which has the disadvantage of increasing costs.

[Purpose of invention]

In view of the above-mentioned drawbacks, the present invention has been proposed by dividing a tape recorder into a tape running unit section and a tape winding unit section, so that necessary parts can be assembled into each unit section, thereby reducing assembly costs and parts. To propose a two-part tape recorder that can perform functional inspection in an assembled state to reduce inspection costs, and when there is a change in function, only the relevant unit part side is changed to reduce the cost due to the change.

[Structure of the idea]

The present invention consists of a tape running unit section in which a flywheel is provided between a lower board that supports a motor and an upper board that supports a head board, pinch arm, etc. so as to be driven by the motor, and a tape running unit that rotates a reel shaft. It is comprised of a tape winding unit portion which is freely supported, is sandwiched between the upper and lower substrates, and is fixed with screws.

〔Example〕

Hereinafter, the present invention will be explained with reference to an illustrated embodiment. 2
In the split-type tape recorder, as shown in FIGS. 1 to 3, a tape running unit part A and a tape winding unit part B are separably combined and connected by two screws 10.
is fixed.

The tape running unit A has upper and lower substrates 1 and 2.
are held in parallel by a plurality of supports 11. A head board 3 is provided on the upper board 1 so as to be able to slide back and forth, and a pinch arm 4 is rotated in conjunction with the back and forth movement of the head board 3 to move the pinch roller 1.
2 is pressed against the capstan shaft 13 with a tape in between. The capsistan shaft 13 is rotatably supported on the upper substrate 1.

The tape recorder shown in the drawing is a reverse type tape recorder in which the magnetic head 14 is reversed, and is provided with two sets of a capstan shaft 13 and a pinch roller 12. Capstan shaft 1 between upper board 1 and lower board 2
3 and 13 are flywheels 1 that also serve as pulleys
5 and 15 are fixed, and the belt 18 is rotated by the rotation of the pulley 17 of the motor 16 fixed to the lower side of the lower board 2.
The flywheels 15, 15 are rotationally driven in a fixed direction via the .

An eccentric cam gear 19 is provided on the lower side of the upper substrate 1 for sliding the head substrate 3 back and forth and reversing the magnetic head 14. A pinion 20 meshed with the eccentric cam gear is connected to the tape winding unit B.
It is protruding from the side.

In the tape winding unit part B, a base 5 is made of a synthetic resin material, and two perforated supports 5a are integrally formed on the lower side of the base 5 as shown in FIG. The base 5 is sandwiched between the upper board 1 and the lower board 2 of the tape running unit A, and screws 10 are inserted into the hole 1a of the upper board 1 and the hole of the support 5a, and are inserted into the screw hole 2a of the lower board 2. A screw 10 is screwed together. A pair of reel shafts 6, 7 are rotatably supported at positions on the base 5 corresponding to the capstan shafts 13, 13, and are urged upward by springs (not shown). A reel shaft drive motor 21 is fixed to the lower center of the base 5. A pinion 22 is fixed to the rotating shaft of the motor 21, and a boss portion 5b is formed on the base 5 around the rotating shaft, and the reversing member 8 is rotatably fitted into the boss portion 5b. A large and small double gear 9 is supported on a shaft 23 at the free end of the reversing member 8 . The large gear 9a of the gear 9 is always meshed with the pinion 22, and when the reversing member 8 is reversed to the right or left depending on the rotation direction of the motor 21, it meshes with the gear 6a of the reel shaft 6 or the gear 7a of the reel shaft 7. be done. The small gear 9b of the gear 9 is connected to the pinion 2 of the tape running unit A when the large gear 9a does not mesh with the gears 6a and 7a.
It is meshed with 0.

When a two-part tape recorder is configured as described above, the parts that were previously inside and could not be seen from the side can now be seen clearly, as shown in the tape winding unit part B in Figure 2, making assembly work easier. Become. The same applies to the tape running unit A, and the tape running unit A and the tape winding unit B can be assembled as a unit, thereby reducing the assembly cost.

Further, by rotationally driving the motor 16 of the tape running unit A and meshing the pinion 20 with a gear of an external drive source for testing, the function of the tape running unit A can be independently inspected, thereby reducing inspection costs. The function of the tape winding unit B can also be independently tested by rotating the motor 21.

Also, when adding or changing a function of the tape winding unit B that is not related to the function of the tape running unit A, the parts attached to the base 5 may be changed to match the functional parts, or the shape of the base 5 may be changed. Since the tape running unit A side can be assembled as is by changing only the tape running unit A side, the cost associated with the change can be reduced. Tape winding unit B
The same applies to the case of changing the function of the tape running unit A which is not related to the function of the tape running unit A.

In the above description, the tape winding unit B is mounted on the base 5, the reel shafts 6 and 7, the motor 21, and the reversing member 8.
Although the base 5 is constructed by attaching functional parts such as, the base 5 may be constructed from upper and lower boards.

The tape running unit A may be implemented in a tape recorder in which the magnetic head is fixed and is moved forward and backward by a control lever.

[Effect of idea]

Since the present invention is constructed as described above, it is easy to assemble, the assembly cost and inspection cost are reduced by forming parts, and the function of either the tape running unit or the tape winding unit is When making additions or changes, only one side needs to be changed, so it is possible to provide a two-part tape recorder that has excellent practical effects, such as reducing the cost of changes.
