So as to achieve accurate detection of the bonding tool position in, for instance, a wire bonding apparatus, the positional relationship between a position detection camera and a reference hole formed in, for instance, a clamper is measured by imaging the reference hole by the position detection camera. The position detection camera and a bonding tool are moved by an XY table, and the tip end of the bonding tool is inserted into the reference hole. Then, the bonding tool is moved in the X and Y directions, and the contact of the bonding tool to an edge of the reference hole is detected based upon changes in the waveform of the ultrasonic vibrations applied to the bonding tool, thus measuring the positional relationship between the tool and the reference hole. The offset amount between the position detection camera and the bonding tool is then determined based upon the measured values and the amounts of movement of the bonding tool between the locations for such measured values.

According to the present invention there are provided method and apparatus for producing a simple printing plate having open cells, which method and apparatus area simple in construction and permit accurate and continuous production of the printing plate. More specifically, as the method there is provided a method of producing a simple printing plate having open cells by pressing both an embossing member having a relief image and a to-be-embossed member which is a sheet having open cells, in a heated state of the embossing member, allowing the relief image to be transferred to the to-be-embossed member, characterized in that the embossing member is attached to an embossing cylinder, the to-be-embossed member is attached to a to-be-embossed cylinder, one or both of the embossing cylinder and the to-be-embossed cylinder being in an arcuate form, and both cylinders are rotated in synchronism with each other, thereby pressing the embossing member and the to-be-embossed member in a rolling fashion.

In bonding machines such as a wire bonding machine, a lock which makes the changing of bonding data impossible is placed on specific data setting mode items, which are stored in a memory, via a data setting mode locking circuit. The changing of data in such locked data setting modes is made possible only if a password inputted is the same as a previously set-in password.
