Abstract: There is provided casting equipment including a control device that acquires, regarding multiple processes in the casting equipment, specific data regarding casting molds in each frame, and that associates the specific data for the respective processes with the casting molds, separately for the casting molds in each frame; and a display device provided, with respect to a first process among the multiple processes and a second process later than the first process, on equipment for executing the second process. The control device displays, on the display device, the specific data for the first process associated with the casting molds that are to be processed in the second process.

Abstract: [Problem] To provide casting equipment and a casting method that can easily track and extract measurement data across multiple processes. [Solution] There is provided casting equipment 1 comprising a control device that acquires, regarding multiple processes in the casting equipment 1, specific data regarding casting molds in each frame, and that associates the specific data for the respective processes with the casting molds, separately for the casting molds in each frame; and a display device provided, with respect to a first process among the multiple processes and a second process later than the first process, on equipment for executing the second process; wherein the control device displays, on the display device, the specific data for the first process associated with the casting molds that are to be processed in the second process.

Abstract: A rotation detector has a rotation disc which is rotatably held on a rotation shaft, a plurality of teeth which are arranged on a surface of the rotation disc along an external periphery thereof, and at least one reflective photocoupler which is positioned slightly away from a surface of the rotation disc and opposed to the teeth. Light is emitted from the reflective photocoupler and impinges on the teeth of the rotation disc 1. The incident light is reflected by the teeth, and impinges on the reflective photocoupler. This rotation detector detects the rotation angle and rotation speed of the rotation disc, based on the receiver's optical outputs. Provision of a second reflective photocoupler enables the device to detect the direction of rotation.

Abstract: In a photo-coupling device, a light emitting section, a light receiving section are housed in an opaque case so as to be opposed with respect to an object moving path intervening therebetween. The light emitting section and the light receiving section are provided with a light-projecting window and a light-receiving window on their opposite opaque case-wall-surfaces, respectively. A holder for holding the light emitting section or the light receiving section is arranged between the light emitting section and the light-projecting window and/or between the light receiving section and the light-gathering window. A light shading plate having a slit is attached to the holding means, and means for positioning the holder with the aid of the contact of the holding means with the case is attached to the case.
