If the above-mentioned circuit boards 2, 3, 4, and 5 are integrally formed, a large circuit board with a punched-out window in the center through which the touch panel display surface 1 can be seen would be required, which would increase the size of the device. Since this poses a problem of high manufacturing costs, it is customary to form each of the circuit boards 2 to 4 independently and separately. Light emitting element groups 7 and 8 each having a plurality of light emitting elements 6 are provided on the adjacent circuit boards 2 and 3, while circuits facing the circuit boards 2 and 3, respectively, are provided. On the substrates 4 and 5 are the light emitting elements 6 and 5.

ひいてはコストの低減化を促し得るといった効果を奏す
る。As described above, the optical sensor type input detection device according to the present invention has a structure in which light emitting elements and light receiving elements are alternately arranged on each circuit board. As a result, the arrangement of the types of photosensor elements placed on each circuit board is all the same, so only the type of length of the circuit board needs to be considered, and therefore the number of types of circuit boards can be halved. . For example, in the case of this embodiment, since there are two types of circuit boards, long and short, it is sufficient to fabricate two types of circuit boards with different lengths. As a result, the productivity of circuit boards has improved significantly,
This also has the effect of promoting cost reduction.

数か奇数かについては具体的に限定しないものである。Further, when manufacturing a circuit board, a long circuit board in which light emitting elements and light receiving elements are arranged alternately is formed in advance, and at the stage of incorporating it into a display device having a touch panel display surface of various shapes and sizes, It becomes possible to use this by appropriately cutting it into a size that fits this. Therefore, there is no need to select the type of element and individually manufacture a circuit board according to the dimensions of touch panel display surfaces having different sizes and shapes, and there is an advantage that the circuit board can have versatility. Moreover, it can be easily adapted to the shape of the touch panel display surface forming the display. This further improves the productivity of circuit boards and makes it possible to further reduce manufacturing costs. Although it is desirable that the number of optical sensor elements arranged on one circuit board be an even number, there is no specific limitation as to whether the number is an even number or an odd number.
