Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an interface device used to connect a small electronic calculator to other equipment.

For example, when connecting a small electronic calculator with a program to a tape recorder for program storage, an interface device with a built-in control circuit that matches the operating voltage and operating speed of the two is used to interface the computer. The interface device is removably attached to and connected to the device, and the interface device is further connected to the tape recorder.

Conventional interface devices have a mounting section on which a computer is placed, and a fixing section that removably holds both sides of the computer placed on this mounting section. The structure is configured such that the size corresponds to the width dimension between both sides of the case of the calculator model, and the specific model calculator is fixedly connected to the fixed part. In other words, conventional interface devices are designed specifically for one type of calculator and are used only for a specific model of calculator, so they cannot be used with other models of calculators that have different widths between the two sides of the case. It could not be used. For this reason, interface devices are not versatile; for example, even if a new interface device is manufactured to accommodate a new model of computer whose case width has become larger due to improved functionality, There was a problem that made the calculator unusable due to its small dimensions.

The present invention was made in consideration of the above circumstances, and
The object of the present invention is to provide an interface device having great versatility, which can be attached and connected to a plurality of types of small electronic calculators each having a different dimension between at least one pair of opposing edges of the case.

Embodiments of the present invention shown in the drawings will be described below.

The embodiment shown in the drawings shows a case in which one type of interface device is attached and connected to two types of small-sized programmable electronic calculators having different widths between both sides of the case. In the figure,
1 and 1' are small electronic computers each equipped with a program function, and 2 is an interface device. The small electronic calculators 1 and 1' are equipped with a plurality of key switches 4 such as function keys and numeric keys on the upper surface of cases 3 and 3 made of synthetic resin, and a display device is disposed inside to display various information. A window 5 is provided, and a recessed connector 6 is provided on the edge surface of one end edge 3d of the case 3 to be connected to a tape recorder (not shown) or the like, that is, to be directly connected to a connector 15 of the interface device 2. is provided at a predetermined position based on the edge surface of one side edge 3a of the case 3. These small electronic calculators 1, 1' have cases 3, 3 with different external dimensions, and the width l between the opposite side edges 3a, 3b of the case 3 of one calculator 1 is different from that of the other. It is smaller than the width l' between the mutually opposing side edges 3a and 3b of the case 3 of the calculator 1'. In addition, in this embodiment, each computer 1, 1'
The length dimensions between the two end edges of the cases 3, 3 are also different. In addition, one small electronic calculator 1
On the edge surfaces of both side edges 3a and 3b of the case 3, a first engaging portion 7 and a second engaging portion 8, which are linear rib-shaped, are located near the one end edge 3d along the longitudinal direction of the case. They are formed so as to face each other. On the edge surface of one side edge 3a of the case 3 of the other small electronic calculator 1', a first engaging portion 9 in the form of a linear rib extends in the longitudinal direction of the case at a location near the one end edge 3d. A second engaging portion 10 is formed along the lower surface portion 3c at a location close to the other side edge portion 3b so as to face the first engaging portion 9. As shown in FIGS. 5 and 6, the second engaging portion 10 is a recess formed inside the lower surface 3c of the case 3 and opens at the lower surface 3c. An insertion portion 10a into which the second engagement portion 17 of the face device 2 is removably inserted is engaged with the second engagement portion 17 adjacent to a portion of the insertion portion 10a near one edge of the case. It is composed of a stepped engagement portion 10b.

The interface device 2 has a planar mounting portion 12 formed on the upper surface of a case 11 made of synthetic resin and having a size that allows the case 3 of the small electronic calculator 1' to be placed, that is, the width and length. There is,
Each computer 1, 1'
A side surface 13 is formed on which one side edge 3a of the cases 3, 3 comes into contact, and an end surface 14 is formed on one end edge of the mounting section 12, on which one end edge 3d of the case 3 comes into contact. Each computer 1, 1'

This connector 15 serves as a computer built into the case 11 and is connected to a control circuit for matching the operating speed and operating voltage of the tape recorders. In addition, the end surface portion 1 of the side surface portion 13 of the case 11
Case 3 of each computer 1, 1' is shown in the part near 4.
A groove-shaped first engaging portion 16, in which the first engaging portions 7 and 9 of the three members are removably engaged, is formed along the longitudinal direction of the side surface. On the surface of the mounting portion 12, at a location close to the other side edge, there is a hook shape that removably engages with the second engaging portions 8, 10 of the cases 3, 3 of each computer 1, 1'. The second engagement portion 17 having a piece-like shape is
It is provided opposite to the first engaging portion 16 and protrudes upward. The distance between the first engaging portion 16, that is, the side surface portion 13, and the second engaging portion 17 is the same as the width between the side edges 3a and 3b of the case 3 of the small electronic calculator 1. , and the one side edge 3a and the second edge of the case 3 of the small electronic calculator 1'.
This is the same size as the distance from the engaging portion 10. The case 11 is provided with a mode changeover switch 18 and a connection cable 19 for connection to other electronic equipment such as a tape recorder.

When connecting one of the small electronic calculators 1 to the interface device 2, the case 11 of the interface device 2 is placed with the case 3 of the computer 1 in the orientation shown in FIGS. 1 and 2. Part 12
