  The present invention relates to teaching materials for electronic circuit learning, and in particular, it is easy for the instructor to give instructions to the learner, and the learner can easily understand the instructions of the instructor without fail. However, even when teaching multiple learners at the same time, the learner can make progress easier while learning by visually checking the electronic circuit pattern printed on the printed circuit board against the mounting. The present invention relates to teaching materials for electronic circuit learning.

  Conventionally, various electronic circuit learning devices and teaching materials for electronic circuit learning have been proposed, for example, Japanese Patent Application Laid-Open No. 2004-317601 and Japanese Patent Application Laid-Open No. 2001-42763.

  JP 2004-317601 A   Japanese Patent Laid-Open No. 2001-42763

  Japanese Patent Laid-Open No. 2004-317601 “Electronic Circuit Learning Device” provides a predetermined signal in response to a control signal supplied from a personal computer to a substrate support that supports an experimental substrate in which a large number of conductive lands having a predetermined pattern are formed on an insulating substrate. A signal processing unit that digitizes and outputs the signal generated and supplied to the measurement terminal is output, and the output signal digitized by the signal processing unit is processed inside the personal computer and displayed on the display device. .

  Japanese Patent Laid-Open No. 2001-42763 discloses an electronic teaching material in which leads of electronic components such as diodes, resistors, light-emitting diodes, transistors, capacitors, and ICs are inserted into holes in the universal substrate and held without soldering. Numbers and alphabets are printed on the surface of these, which can indicate the position of electronic components, and the user picks up the electronic components from the universal board to realize the functional circuit while looking at the circuit diagram, The desired functional circuit can be manufactured and the circuit experiment can be performed by mounting the picked-up electronic component on the universal board or another wiring board that has been emptied by removing the electronic component and soldering the wiring. It is.

  However, none of the cited references described above can advance learning while visually recognizing the electronic circuit pattern printed on the printed circuit board in contrast to the mounting, like the teaching material for electronic circuit learning of the present invention. It was.

  The cited document 1 is a large-scale device. In the cited document 2, the user picks up the component name of the electronic component for realizing the functional circuit while looking at the circuit diagram. It is to be mounted on another board, and it is described that the workability and efficiency at the time of using electronic components are improved, and that the user can learn to decide the layout and the like by himself / herself.

  These cited references were not able to make learning progress while visually comparing the electronic circuit pattern printed on the printed circuit board with the silk screen, unlike the teaching material for electronic circuit learning of the present invention.

  A printed wiring that is conductively connected to a position corresponding to an electronic circuit diagram printed on a silk screen on a printed circuit board, and an electronic component corresponding to a component symbol on the electronic circuit is attached, and a plurality of prints An electronic circuit diagram consisting of a plurality of circuit groups is printed on a substrate by a silk screen printing method, and a learner visually recognizes an electronic circuit pattern printed on a printed circuit board as opposed to mounting. Provided is a learning material for electronic circuit learning, characterized in that learning can be progressed.

  According to the electronic circuit learning material of the present invention, since various electronic circuit patterns are silk-screen printed on a plurality of printed circuit boards, it is easy for the instructor to give instructions to the learner. Without a doubt, it can be easily grasped. In addition, in the group of engineers and school education, even when teaching multiple learners at once, the learner can make progress while visually observing the electronic circuit pattern printed on the silk screen on the printed circuit board. Can be made easier.
