Description

[Detailed description of the invention] This invention relates to a mounting structure for a program cassette, and in particular, in an electronic device that is electrically driven by a battery, the program cassette is attached to the battery cover so that the battery cover doubles as the main body of the program cassette. The present invention relates to a mounting structure for a program cassette.

Recently, in electronic devices such as electronic desktop calculators, electronic cash registers, and electronic dictionaries, semiconductor devices such as memory and LSI that store programs to achieve the original operation of the electronic device have been made removable. In order to make programs easier to change and compatible, some electronic devices are equipped with removable program cassettes.

In a conventional program cassette mounting structure, a space dedicated to mounting the program cassette is provided in a part of the exposed portion of the main body of the electronic device, and a program cassette mounting mechanism is separately provided in the space.

For this reason, the mechanism for attaching the program cassette becomes complicated, and its assembly becomes difficult, resulting in an increase in the price of the electronic device.

Furthermore, since a space dedicated to installing the program cassette must be provided, there is also the problem that the electronic device main body cannot be made smaller.

Therefore, this idea was made to solve the above-mentioned problems, and it is possible to simplify the mounting structure of the program cassette and to reduce the size of the electronic device itself without requiring a dedicated mounting space. , the purpose is to provide a mounting structure for a program cassette.

To summarize this idea, in an electronic device with a built-in battery, the structure of the program cassette can be simplified and downsized by configuring the program cassette to be attached to the battery cover that covers the outer part of the battery. It was planned.

Embodiments of this invention will be specifically described below with reference to the drawings.

Figure 1 shows a program cassette 10 of an embodiment of this invention.
FIG. 1A is an illustrative view showing the mounting structure of the battery, in particular, FIG. 1A is a plan view seen from the back side of the battery cover, and FIG.

In the configuration, a battery cover 11 that can be attached to and detached from an electronic device to be described later.
A positioning frame member 111 for mounting the program cassette board 12 is formed on the back side thereof, and a locking portion 112 for locking to the electronic device main body is formed at one end in the longitudinal direction.
is formed, and a bent portion 113 is formed at the other end in the longitudinal direction.

The program cassette board 12 has a planar shape that is equal to or slightly smaller than the planar shape of the frame portion 111 formed on the battery lid 11, and has a circuit element 13 electrically connected to one surface thereof in a desired circuit pattern. A circuit pattern has been formed for this purpose.

The circuit element 13 is a memory storing a program to achieve the operation of the electronic device or an LS for performing other operations.
I, etc., and its lead terminals are electrically connected to the circuit pattern of the program cassette board 12 as appropriate.

On the other side of the program cassette board 12, one end of a terminal 14 electrically connected to the circuit pattern is embedded or fixed.

The other end of the terminal 14 is bent so as to protrude from the upper surface of the frame member 111 and have elasticity when the board 12 is inserted into the frame member 111.

The open end of the terminal 14 is preferably bent into an arc to improve electrical contact.

A program cassette board support plate 15 is provided to support the program cassette board 12 within the frame member 11.

This support plate 15 has a through hole 151 that can expose a plurality of terminals 14 formed on the other side of the substrate 12, and the longitudinal end thereof is a recess ( or a groove).

When assembling the components configured as described above and integrally attaching the program cassette to the battery cover 11, first insert the circuit elements 13 of the board 12 into the frame member 111 of the battery cover 11.
The plurality of terminals 14 are inserted into the support plate 1 with the mounting surface facing downward.
The program cassette board 1
2 is detachably attached to the battery cover 11.

The substrate 12 attached in this manner can be freely replaced by removing the support plate 15.

Note that if it is not necessary to replace the program cassette board 12 or if it is replaced integrally with the battery cover, the program cassette board may be integrally fixed to the battery cover 11 by welding with resin or the like. good.

In this case, replace the program cassette using the battery cover 11.
However, by replacing the program cassette board integrally with the battery cover when replacing the program cassette board, there is an advantage that the effort of removing the support plate 15 and replacing the program cassette board 12 can be saved.

FIG. 2 is an illustrative view showing the state in which the program cassette 10 according to the embodiment of this invention is attached to an electronic device, and particularly shows a longitudinal sectional view thereof.

Next, as shown in Figure 1 (configured program cassette 1
0 to the main body of the electronic device 20 will be explained.

The electronic device 20 has guides 211 and 212 for mounting the battery 22 inside its main body 21, and a battery cover fitting hole having the same shape as the battery M11 is opened above the mounting part of the battery 22. The locking portion 112 is located at the battery cover attachment portion.
A locking portion 213 is formed that engages with.

Further, inside the main body 21, there is provided a board 23 on which a suitable circuit pattern is formed on portions corresponding to the plurality of terminals 14 formed on the program cassette board 12.

Then, the battery cover 11 is fitted into the battery cover fitting hole of the main body 21 with the program cassette board mounting side facing inside, and the locking part 112 of the battery cover 10 and the locking part 113 of the main body are engaged, so that the battery The lid 11 is integrally attached to the book front 21.

At this time, the plurality of terminals 14 formed on the program cassette board 12 attached to the battery cover are press-connected to the corresponding portions of the circuit pattern on the board 23 provided inside the electronic device 20, thereby causing the circuit The element 13 will be electrically connected to the circuit pattern on the substrate 23.

In addition, the battery 2
By pressing 2, the battery 22 is pressed and fixed.

In this way, by attaching the battery cover with the program cassette attached to the main body of the electronic device, the terminals 14 have appropriate elasticity, so that printed wiring etc. formed on the board of the electronic device 20 can be easily connected. It has the advantage that sufficient electrical connection can be obtained by press-contacting the circuit pattern.

As described above, according to this invention, the mounting part of the program cassette can be shared with the mounting part of the battery, which simplifies the mechanism, requires no special space, and can be installed in the minimum space, and the program cassette itself The unique effects are that the price is low and the loading and unloading of the program cassette can be performed extremely easily.
