Abstract: A thickness measuring device of a laminating machine includes a mount, a stepper motor, a screw rod, a first contact-activated element, a second contact-activated element, and a microcontroller unit. The stepper motor is coupled to the mount. The screw rod is interlocked with the stepper motor. The first contact-activated element is provided at a position corresponding to and some distance below the screw rod. The second contact-activated element is provided at a position corresponding to and some distance above the screw rod. The microcontroller unit is electrically connected to the stepper motor, the first contact-activated element, and the second contact-activated element so as to provide initialization setting and exercise judgment and control after receiving a thickness measurement. Thus, the thickness of an object to be detected can be conveniently measured.

Abstract: A computer chassis has a post assembly, a motherboard holder, a guardian board and a mounting board. The post assembly has a first post, a second post and a power supply holder. The motherboard holder is detachably mounted to one of the first post and the second post. The guardian board is detachably mounted between the first post and the second post. The mounting board is detachably mounted between the first post and the second post. The arrangement of the motherboard holder, the guardian board and the mounting board may be changed to make the computer chassis compatible with an ATX motherboard or a BTX motherboard.
